Hi I am writing a simple console app that needs to write bytes to MCP2210 USB to SPI Master
I found this library over here , seems to do good job with connecting the device and reading the metadata.
I am writing message to the board as below
public static byte[] Talk()
{
var device = DeviceList.Local.GetHidDevices(1240, 222).FirstOrDefault();
if (device == null)
{
Console.WriteLine($"Could not find a device with Vendor Id:1240, Product Id:222 ");
return null;
}
var reportDescriptor = device.GetReportDescriptor();
foreach (var deviceItem in reportDescriptor.DeviceItems)
{
Console.WriteLine("Opening device for 20 seconds...");
if (!device.TryOpen(out var hidStream))
{
Console.WriteLine("Failed to open device.");
continue;
}
Console.WriteLine("Opened device.");
hidStream.ReadTimeout = Timeout.Infinite;
hidStream.Write(new byte[3] {60, 00, 00});
}
Not sure If I am writing it correctly. While writing I need to do a chip selection as displayed in this other terminal
Any help is greatly appreciated
Here is the MC I am using https://www.microchip.com/wwwproducts/en/MCP2210
I do not see a closing of your stream. This may cause your data to not even being sent (at least not in time).
Consider using blocks with streams. But with out parameters not possible.
